Under 10 per cent of IPv4 addresses are left

[zanzabar]

is it just me or is the math a little off:

only class a b and c addresses can be given out but there are also class d (multicast) and e (experimental), then u have the private network addresses also that cannot be assigned on the internet

I have not been trained in IPv6

My networking had only IPv4 ahhh i am obsolete...

same here i only have ipv4 training.


also why did they use the : instead of the . how do u express ports in ipv6
